A new device designed to measure the amount of milk a breastfed baby consumes could alleviate parental anxiety regarding breastfeeding. Developed by researchers at Northwestern University, this innovative tool employs four electrodes that adhere to the breast and utilize weak electrical currents to gauge milk volume in real time.
The concern among parents often stems from the uncertainty of how much milk their baby is receiving, which can lead to stress for both parents and healthcare providers. Traditional methods for assessing breastfeeding efficacy, such as weighing infants before and after feeds, are considered cumbersome and imprecise. The new device aims to provide a more accurate measurement by calculating milk release based on the changes in electrical signals as milk is expressed.
In initial tests involving twelve breastfeeding women using breast pumps, the device estimated milk volumes with a margin of error of approximately two milliliters, indicating a high degree of accuracy. When one participant used the device while breastfeeding, the app calculated an intake of 24 milliliters, closely aligning with the 20 milliliters estimated using conventional weighing methods.
Experts believe that this technology could help parents monitor their babies' nutritional intake, potentially guiding decisions on supplementing with formula if necessary. However, further research is essential to confirm the device's accuracy in larger populations, evaluate any effects on milk production, and determine parental acceptance of the technology. As the study progresses, it may provide valuable insights into optimizing breastfeeding practices and alleviating concerns related to milk supply.
